About the Mineral Kyanite
The mineral kyanite is a natural stone that's not particularly common whose name comes from the Greek word "kyanos" meaning "blue". Despite being brittle this mineral is widely used in industry primarily because of its exceptional hardness but also because of its ability to tolerate heat. When kyanite is heated the stone expands and in some cases can even double in size.
Kyanite is a translucent mineral with a vitreous lustre that's known for its zones of colour and variation in hardness. Whilst most natural minerals have one hardness kyanite plus a few others have two. Crystals tend to form as long narrow blades which grade 4 to 5 on Mohs scale when tested lengthways and 6 to 7 when tested across the width of the same crystal. This characteristic along with it being brittle makes kyanite an extremely challenging stone to cut.
Being so fragile means that it's not ideal as a gemstone but is still used in selective items of jewellery. The stone must always be handled carefully because it can be damaged easily. When used as a gemstone it tends to be faceted and can often have a "scratchy" appearance and/or other minor surface marks. The colour of the finest grade stones can rival the colour of a sapphire.
In the metaphysical world of crystal healing along with the mineral citrine, kyanite does not accumulate or retain negative energy so rarely needs to be cleansed. It's a stone of tranquillity which stimulates communication and psychic awareness and has the ability to align the chakras. It can help one to persevere in activities and situations which would usually reduce strength. Kyanite can be used to balance yin and yang and dispel energy blockages.
This distinctive mineral can be found in the United States, Brazil, Switzerland, Russia, Serbia, India and Kenya. Fine gem quality kyanite crystals have also been mined in Nepal though exact quantities are unknown.
